Vulvar Cancer, Version 3.2024, NCCN Clinical Practice Guidelines in Oncology.

Vulvar cancer is annually diagnosed in an estimated 6,470 individuals and the vast majority are histologically squamous cell carcinomas. Vulvar cancer accounts for 5% to 8% of gynecologic malignancies. Known risk factors for vulvar cancer include increasing age, infection with human papillomavirus, cigarette smoking, inflammatory conditions affecting the vulva, and immunodeficiency. Most vulvar neoplasias are diagnosed at early stages. Rarer histologies exist and include melanoma, extramammary Paget's disease, Bartholin gland adenocarcinoma, verrucous carcinoma, basal cell carcinoma, and sarcoma. This manuscript discusses recommendations outlined in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for treatments, surveillance, systemic therapy options, and gynecologic survivorship.

Extramammary Paget disease. Part II. Evidence-based approach to management.

Extramammary Paget disease is a rare cutaneous malignancy that most commonly affects the genitals, perianal area, and axilla of elderly patients. Delays in care often lead to high levels of disease burden for patients. Thus, evidence-based recommendations are paramount in mitigating morbidity and mortality for this unique patient population. This 2-part continuing medical education series provides a complete picture of extramammary Paget disease. Part 2 of this continuing medical education series focuses on the complex management of extramammary Paget disease including surgical and noninvasive therapies, as well as novel approaches for advanced disease.

Extramammary Paget disease. Part I. epidemiology, pathogenesis, clinical features, and diagnosis.

Extramammary Paget disease (EMPD) is a rare skin cancer of apocrine-rich skin that mimics common inflammatory and infectious dermatoses, leading to delays in diagnosis and increased patient morbidity. Better clinical recognition of this entity, multidisciplinary patient assessment, and deeper understanding of the underlying pathophysiology are essential to improve patient care and disease outcomes. It is important to distinguish primary intraepithelial/micro-invasive EMPD from invasive EMPD or cases with adenocarcinoma arising within EMPD. This 2-part continuing medical education series provides a complete picture of EMPD. Part 1 of this continuing medical education series reviews the epidemiology, oncogenesis, clinical and histopathologic presentation, workup, and prognosis of this rare cancer.

Extramammary Paget's Disease of the Scrotal and Penile: A Case Report and Review of the Literature.

INTRODUCTION: Extramammary Paget's disease of the scrotum and penis is a relatively rare cutaneous malignant tumor. At present, its pathogenesis, and clinical and pathological characteristics are not very clear. This is controversial regarding surgical margin width to decrease the high recurrence rate. This paper aimed to report the case and review the literature of extramammary Paget's disease of scrotum and penis. CASE PRESENTATION: We presented the case of a 74-year-old male patient with the patchy erythema and pruritus in the perineum who was admitted to our department. Biopsy of the large plaque revealed Paget disease. Under the condition of ensuring negative surgical margins by rapid frozen pathology, a wide local excision of the lesion, bilateral orchiectomy, and adnexectomy were performed on the patient. Pathology revealed that many scattered vacuolated Paget cells were observed in the epidermal layer, and the diagnosis was Paget's disease of the scrotum and penis. The 2 cm outside the skin lesion was used as the initial surgical margin, and free skin flap transplantation was used to repair the surgical wound. The patient recovered well and was discharged 1 week after surgery. CONCLUSION: Currently, histopathologic biopsy is the most important diagnostic method for EMPD. Once confirmed, for patients eligible for surgical intervention, wide local excision of the lesion and rapid intraoperative frozen pathological examination should be performed as soon as possible. The skin flap transplantation is the first choice for the repair of large-scale wound after surgery.

A Rare Case of Axillary Extramammary Paget's Disease with an Underlying Adenocarcinoma.

Extramammary Paget's disease (EMPD) is an uncommon cutaneous neoplasm almost exclusively located in the vulvar, perianal, and male genitalia regions. Evaluation and management are complicated given the average delay in diagnosis is two years and approximately 30% of cases are associated with underlying malignancies. The axilla is a unique location for EMPD. We report a rare case of a 78-year-old male with axillary EMPD associated with an underlying adenocarcinoma. A 1-cm tender and pruritic erythematous plaque with surrounding erythema appeared in the patient's axilla. An irritated seborrheic keratosis secondarily impetiginized along with irritant contact dermatitis was suspected. Treatment of cefdinir and topical hydrocortisone failed and a biopsy was taken. Microscopic and immunohistochemical examination showed ulceration with an underlying proliferation of atypical glands (Figure 2A) and a nested intraepidermal proliferation with pagetoid spread (Figure 2B). The atypical cells were positive for gross cystic disease fluid protein 15 (Figure 2C), epithelial membrane antigen (Figure 2D), cytokeratin 5/6, and cytokeratin 7. These findings were supportive of an apocrine adenocarcinoma arising in association with EMPD. Wide location excision was performed. Screening for associated malignancies or lymphatic spread is the primary goal during evaluation. Outcomes are favorable when the primary neoplasm is of limited distribution. The accepted treatment for primary lesions is wide local excision, although anatomic tissue constraints necessitate further research into other treatment modalities. To our knowledge, this is the 14th reported case of axillary EMPD with an underlying adenocarcinoma which may help with identification and management of future cases.

The elusive extremities: a case of extramammary Paget disease.

Extramammary Paget disease is a rare dermatological condition resembling Paget disease that occurs most commonly in the anogenital area and axilla. We present the case of an elderly male who had come with complaints of an itchy, erythematous and raised lesion in the perianal region for 3 months that did not respond to antifungals. A biopsy was taken from the lesion site and the diagnosis was confirmed by histopathological examination. It is important to be aware of conditions like extramammary Paget disease when an elderly individual presents with a non-specific pruritic lesion in the perianal area that is non-responsive to treatment; the diagnosis of which can be made only by doing a biopsy from the concerned site. This highlights the importance of histopathological examination in such ambiguous cases.

Anatomic Subtype Differences in Extramammary Paget Disease: A Meta-Analysis.

Importance: Extramammary Paget disease (EMPD) is a rare, highly recurrent cutaneous malignant neoplasm of unclear origin. EMPD arises most commonly on the vulvar and penoscrotal skin. It is not presently known how anatomic subtype of EMPD affects disease presentation and management. Objective: To compare demographic and tumor characteristics and treatment approaches for different EMPD subtypes. Recommendations for diagnosis and treatment are presented. Data Sources: MEDLINE, Embase, Web of Science Core Collection, and Cochrane Reviews CENTRAL from December 1, 1990, to October 24, 2022. Study Selection: Articles were excluded if they were not in English, reported fewer than 3 patients, did not specify information by anatomic subtype, or contained no case-level data. Metastatic cases on presentation were also excluded. Data Extraction and Synthesis: Abstracts of 1295 eligible articles were independently reviewed by 5 coauthors, and 135 articles retained. Reporting was in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. The analysis was cunducted in August 2019 and updated in November 2022. Findings: Most vulvar EMPD cases were asymptomatic, and diagnosis was relatively delayed (mean, 25.1 months). Although most vulvar EMPD cases were intraepidermal (1247/1773 [70.3%]), radical surgeries were still performed in almost one-third of cases. Despite this aggressive surgical approach, 481 of 1423 (34%) recurred, commonly confined to the skin and mucosa (177/198 [89.4%]). By contrast, 152 of 1101 penoscrotal EMPD cases (14%) recurred, but more than one-third of these recurrences were regional or associated with distant metastases (54 of 152 [35.5%]). Perianal EMPD cases recurred in one-third of cases (74/218 [33.9%]), with one-third of these recurrences being regional or associated with distant metastasis (20 of 74 [27.0%]). Perianal EMPD also had the highest rate of invasive disease (50% of cases). Conclusions and Relevance: The diagnosis and treatment of EMPD should differ based on anatomic subtypes. Considerations for updated practice may include less morbid treatments for vulvar EMPD, which is primarily epidermal, and close surveillance for local recurrence in vulvar EMPD and metastatic recurrence in perianal EMPD. Recurrences in penoscrotal subtype were less common, and selective surveillance in this subtype may be considered. Limitations of this study include the lack of replication cohorts and the exclusion of studies that did not stratify outcomes by anatomic subtype.

Case report: A case of Paget disease outside the axillary breast.

BACKGROUND: Extramammary Paget disease is a relatively rare and less malignant intraepithelial adenocarcinoma. t is found in areas with abundant distribution of apocrine sweat glands such as the external genitalia, external genitalia, and perianal area, with fewer armpits. The disease progresses slowly and is prone to misdiagnosis in clinical practice. METHODS: We retrospectively analyzed a female patient. She had a left axillary mass for more than 2 years. Recently, the mass increased and the surface skin was ulcerated. Then she went to Jiangxi Provincial Dermatology Hospital for left axillary lesion resection, and the postoperative pathology showed Paget disease outside the breast. For further diagnosis and treatment, she came to our hospital. We diagnosed a tumor with uncertain or unknown dynamics in the left axillary breast. Under general anesthesia, left subaxillary mass resection, freezing and left breast cancer breast conserving surgery was performed. RESULTS: The postoperative pathology of the left axillary mass combined with morphological and immunohistochemical results was consistent with Paget disease. Postoperative immunohistochemistry showed estrogen receptor (+, 20%), progesterone receptor (-), human epidermal growth factor receptor-2 (3+), Ki-67 (30%), cytokine7 (+), and p63 (-). Following up for 22 months, there has been no local recurrence, no swelling of the right axillary lymph node, no distant metastasis found on follow-up, and no complications such as upper limb lymphedema, upper limb sensory abnormalities, or motor disorders have been observed. CONCLUSION: Paget disease outside the axillary breast is relatively rare, and surgical resection is the best choice. The prognosis is good, and the recurrence rate is low.

Electron radiotherapy for EMPD of penis and scrotum.

ABSTRACT: Electron beams represent an important treatment modality for providing an accurate dose of therapy to superficial cancers. This case reports important findings of dermal invasion in patients with extramammary Paget's disease (EMPD) using microscopic measurements and electron beam coverage. EMPD is a rare cutaneous adenocarcinoma generally arising in the anogenital region. Surgery is still a curable treatment option for patients with EMPD, whereas radiation therapy (RT) is an alternative for inoperable cases and is necessary in cases where surgery is not performed. This case report describes our experience and reviews the relevant literature on the feasibility of electron RT according to the dermal invasion length. An 80-year-old patient was diagnosed with EMPD and presented for definite radiation treatment. We observed no grade 3 toxicities during electron RT, and at the last follow-up visit, no signs of relapse were observed. There are no reports of electron irradiation as a feasible treatment option for EMPD considering the epidermal invasion length.

Perianal Paget's disease / Doença de Paget perianal

ABSTRACT Paget's disease most commonly affects the breast. Extramammary involvement is rare, and the most commonly affected sites are the vulva, anus, perianal region, and axilla. The disease may progress to invasive adenocarcinoma or synchronous cancers. Due to the lack of distinctive features and nonspecific presenting symptoms, Paget's disease may be misdiagnosed as other conditions, thus delaying the correct diagnosis. We report a case of extramammary Paget's disease in the perianal region that initially presented as an irregular, circumferential, scaling lesion with eczematous eruptions. Immunology and immunohistochemistry confirmed the diagnosis. Although surgery is the standard treatment, the patient opted for pelvic radiotherapy associated with radiosensitizing chemotherapy.

RESUMO A doença de Paget acomete mais comumente a mama. Os focos extramamários são raros e os locais mais habitualmente acometidos são vulva, ânus, região perianal e axila. A patologia envolve a evolução da doença para adenocarcinoma invasivo ou neoplasias sincrônicas. Devido à singularidade e sua aparência inespecífica, a doença pode ser confundida com outras comorbidades, retardando o diagnóstico. O objetivo foi relatar um caso de doença de Paget extramamária na região perianal, a qual inicialmente apresentou lesão circunferencial com erupção eczematosa, descamativa e irregular. A confirmação diagnóstica foi por meio de exames imuno-histoquímico e imunológico. O tratamento padrão da doença é cirúrgico, porém optou-se por radioterapia pélvica associada à quimioterapia radiossensibilizante.

Enfermedad de Paget extramamaria de la vulva: a propósito de un caso clínico / Extramammary Paget's disease of the vulva: apropos of a clinical case

La Enfermedad de Paget extramamaria de la vulva es una neoplasia poco frecuente que representa solo el 1% de los cánceres de vulva. Clínicamente, se caracteriza por una placa eritematosa, bien definida, con erosiones y ulceraciones. El síntoma más frecuente es el prurito. Esta clínica tan inespecífica puede retrasar el diagnóstico, además de inducir a tratamientos inadecuados. El diagnóstico se realiza con estudio histopatológico e inmunohistoquímica, la cual orienta si es primario de piel o metástasis de otro cáncer, usualmente genitourinario o gastrointestinal subyacente. Actualmente no hay guías clínicas de tratamiento, pero dentro de las opciones la más aceptada es la cirugía de Mohs. Otros tratamientos incluyen uso de imiquimod, láser CO2, quimioterapia tópica o local, radioterapia o terapia fotodinámica. Cuando se trata de una enfermedad de Paget extramamaria primaria, el pronóstico es excelente y la mayoría de los pacientes fallece por otra condición. En cuanto a la enfermedad invasora, tiene una mortalidad de 13-18% con sobrevida a 5 años de 72% (1)

Enfermedad de Paget extramamaria: reporte de caso / Extramammary Paget's disease: case report

Se presenta el caso de una mujer de 67 años de edad, sin antecedentes de importancia, con un tiempo de enfermedad de un año. La paciente refiere una lesión tipo placa amarronada con áreas eritematosas y de bordes definidos, localizada en la región púbica izquierda, con extensión a la región inguinal, asociada a intenso prurito. Se le diagnosticó eccema y recibió tratamiento con corticoides tópicos, sin mostrar mejoría. Al momento de la evaluación, el examen físico no reveló adenopatías y los exámenes de laboratorio resultaron normales. El diagnóstico fue inmunohistopatológico, mediante el hallazgo de células de Paget y la tinción positiva para CK-7 y panqueratina, compatible con una enfermedad de Paget extramamaria, debida a diseminación intraepidérmica de un tumor primario de glándulas sudoríparas tipo adenocarcinoma in situ. La paciente fue sometida a una evaluación general para descartar una diseminación a distancia, pero no se encontró evidencia alguna. Se la trató exitosamente con cirugía escisional estándar con bordes libres y cursó favorablemente sin recurrencias cinco meses después.

A 67-year-old woman presented with a history of one year of pruriginous well defined brownish-reddish patch lesion on pubic area, which extended to inguinal area. An external diagnosis of eccema was made and the patient initiated treatment with topical corticosteroids for several months, without results. At present time, physical examination and laboratory evaluation did not reveal major alteration. A biopsy was taken and immunohistochemistry analysis was made, which revealed the presence of Paget's cells positive to CK-7 and pan Keratin. The results were compatible with extramammary Paget's disease secondary to intraepidermal dissemination of primary apocrine sweat glands adenocarcinoma. The patient underwent further evaluation to rule out distant metastases and was treated successfully with surgical excision alone with free margins. At follow-up five months later was still free of recurrences.
